[PATCH net-next 0/2] of: mdio: Fall back to mdiobus_register() with np is NULL

[Florian Fainelli]

Hi all,

This patch series updates of_mdiobus_register() such that when the device_node
argument is NULL, it calls mdiobus_register() directly. This is consistent with
the behavior of of_mdiobus_register() when CONFIG_OF=n.

I only converted the most obvious drivers, there are others that have a much
less obvious behavior and specifically attempt to deal with CONFIG_ACPI.

[PATCH net-next 1/2] of: mdio: Fall back to mdiobus_register() with np is NULL

[Florian Fainelli]

When the Device Tree node specified is NULL, fall back to
mdiobus_register(). We have a number of drivers having a similar pattern
which is:

if (np)
	of_mdiobus_register()
else
	mdiobus_register()

so incorporate that behavior within the core of_mdiobus_register()
function. This is also consistent with the stub version that we defined
when CONFIG_OF=n.

[PATCH net-next 2/2] drivers: net: Remove device_node checks with of_mdiobus_register()

[Florian Fainelli]

A number of drivers have the following pattern:

if (np)
	of_mdiobus_register()
else
	mdiobus_register()

which the implementation of of_mdiobus_register() now takes care of.
Remove that pattern in drivers that strictly adhere to it.
